Drill bit MEGA SDS+ 14 mm for concrete, model 81430

MEGA SDS+ 14 mm drill bit for concrete, model 81430, is a rotary/percussion masonry bit designed for use with SDS+ hammer drills. With a 14 mm working diameter and a carbide tip geometry optimized for percussion drilling, this bit is intended for making clean, accurate holes in concrete, reinforced concrete and other masonry materials. The straight shank profile fits SDS+ chucks and transmits rotary and impact energy for efficient hole-making during anchoring, fixture installation and general construction tasks.

Advantages

The 14 mm diameter provides a balance between hole size and drilling speed for common anchor and fastening applications. The carbide-tipped head ensures improved wear resistance and maintains cutting performance in abrasive concrete. The SDS+ shank allows quick, secure insertion and removal in compatible hammer drills, while the flute geometry facilitates reliable removal of dust and debris from the hole during drilling.

Suitable for

• Drilling anchor holes for bolts, dowels and chemical anchors in concrete
• Fixing fixtures such as shelves, brackets and electrical boxes to masonry walls
• General construction and renovation tasks in reinforced concrete and masonry

Key specifications

• Diameter: 14 mm
• Design: SDS+ shank for hammer drills
• Tip material: carbide cutting tip for percussion drilling
• Intended materials: concrete, reinforced concrete, masonry
• Application: rotary/percussion drilling for anchors and fixtures

How to use

Select an SDS+ compatible hammer drill and insert the bit into the chuck until it locks. Mark the drilling position and, when drilling into concrete, start at low speed to establish the hole then apply steady pressure while maintaining drill alignment. Use rotary-percussion mode on the hammer drill for efficient penetration. Periodically withdraw the bit to clear dust from the hole and allow the bit to cool. After reaching the required depth, clean the hole of debris before inserting anchors or fasteners.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and dust mask. For best results on reinforced concrete, use progressive drilling with controlled pressure and allow the bit to clear debris frequently. Replace the bit when wear reduces drilling efficiency or when the carbide tip is damaged.
